For U.S. companies, the question isn't whether climate disclosure is coming — it's which rules will actually apply. Unlike Europe's single, harmonized framework, the American landscape is a patchwork: a strong lead from California, a federal rule caught in legal and political crosscurrents, and a large group of companies that keep reporting regardless because investors and customers expect it.
California sets the pace
Two California laws now anchor the U.S. conversation. SB 253, the Climate Corporate Data Accountability Act, requires large companies doing business in the state to report their greenhouse gas emissions. SB 261, the Climate-Related Financial Risk Act, requires a broader set of companies to publish how climate change could affect their business and finances. Because so many national companies do business in California, these state laws effectively set a floor for much of corporate America.
“In practice, California has become the country's climate-disclosure baseline — even for companies headquartered nowhere near it.”
The federal rule is on hold
The Securities and Exchange Commission adopted its own climate disclosure rule in 2024, but it was paused almost immediately amid legal challenges, and the agency later stepped back from defending it. For now, there is no active federal climate reporting requirement — leaving companies to look to the states and to voluntary standards for direction.
Voluntary standards fill the gap
With the federal picture unsettled, many companies anchor their reporting to widely used standards — the ISSB's IFRS S1 and S2, the climate-risk approach popularized by the TCFD, and topic guidance from SASB and GRI. These give investors comparable, decision-useful information no matter how the regulatory debate plays out.
What it means for reporting
- Confirm whether California's SB 253 and SB 261 thresholds apply to you
- Treat a credible, well-documented climate-risk narrative as table stakes, regardless of the federal rule
- Keep your emissions data and methodology consistent across every channel that references them
- Anchor voluntary disclosure to a recognized standard so it stays comparable and durable
Big Pivot Partners helps U.S. companies turn this fragmented picture into clear, credible, and consistent communications — connecting climate and sustainability information to strategy, performance, and long-term value. We work alongside the legal, accounting, and assurance advisers who own the technical compliance questions. For the mechanics of California's first reporting cycle, see our companion piece on SB 253.
